"Open Window" #HDGrid map of left lateral accessory pathway in WPW. Window of interest opened wide to include both A and V. Not important which signal is A or V anymore as we are simply mapping the leak across the annulus. System annotates LAT with abs dVdt. #EPeeps @AbbottCardio
"Open Window" remap during RV pacing. Slide color bar to identify both atrial and ventricular insertion points of the pathway. No manual reannotation required. Just look for the "dragon's breath"! @narrowQRS @DrRoderickTung @MRobinsonEP @NazemAkoum @jordanprutkin @ArunRSridhar
High point density is essential for maximum effectiveness of "Open Window" mapping. #HDGrid identified sharp AP potentials marked at brown dot, between A&V insertion points. @gopi_gdanda1 @MdHuang @MDTolgaAksu @CarinaHardy4 @Ed_Gerst @rdschaller @50wattdoc @DRTomlinsonEP @True_EP
